摘　　要：超级电容器因具有功率密度高、充放电速度快和循环寿命长等优点而备受关注,但是较低的能量密度限制了其广泛应用。开发新型高效电极材料对改善超级电容器电化学性能至关重要。金属有机框架材料(MOFs)具有比表面积大、结构孔径可控和活性位点丰富等特点,故在能量转化和储存领域受到了广泛关注。但是由于MOFs的结构稳定性和导电性较差,其作为超级电容器的电极材料时,无法获得满意的电化学性能。以MOFs为前驱体制得的MOFs衍生物的稳定性和导电性优于原生MOFs,显著提高了超级电容器的电化学性能。本文综述了超级电容器用纳米MOFs衍生碳化物、氧化物、氢氧化物、磷化物、硫化物电极材料的研究现状,总结了MOFs衍生超级电容器电极材料的合成策略,为超级电容器用MOFs衍生纳米材料的研究提供指导意义。Supercapacitors have attracted much attention because of their high power density,fast charging/discharging speed,and long cycle life.However,the low energy density restricted their wide application.Developing novel and efficient electrode materials is imperative to improve the electrochemical performance of supercapacitors.Metal-organic frameworks(MOFs)have attracted extensive attention in the field of energy conversion and storage,owing to their large specific surface area,controllable pore size,rich active sites and easy synthesis.Nevertheless,due to the inferior structural stability and low conductivity of MOFs,the electrochemical performance of supercapacitors with MOFs electrode materials is unsatisfactory.MOFs derivatives,prepared from the MOFs precursor,possess excellent structural stability and conductivity,thus prominently improve the electrochemical performance of supercapacitors.This work mainly focuses on the MOFs-derived electrode materials for supercapacitors,including MOFs-derived carbides,oxides,hydroxides,phosphides and sulfides.The synthesis strategies of electrode materials for supercapacitors are discussed,providing guidance for the research of nano-MOFs-derived materials for supercapacitors.
